    (June 19, 2012)
    Before DUBINA, Chief Judge, EDMONDSON, Circuit Judge, and GOLDBERG,*
    Judge.
    *
    Honorable Richard W. Goldberg, United States Court of International Trade Judge,
    sitting by designation.
    DUBINA, Chief Judge:
    Petitioner Stone & Webster Construction, Inc. (“S&W”) seeks this court’s
    review of Respondent Secretary of Labor’s decision in favor of S&W’s former
    employee, James Speegle, who intervened in this case. In contradiction to the
    findings of an administrative law judge (“the ALJ”), the Secretary’s
    Administrative Review Board (“the ARB”) found that S&W gave pretextual,
    shifting explanations for terminating Speegle and found that Speegle suffered
    disparate treatment in comparison to other similarly situated employees.
    Consequently, the ARB found that Speegle proved S&W fired him for engaging in
    conduct protected by the Energy Reorganization Act (“ERA”). After reviewing
    the ALJ and the ARB’s decisions on liability, reading the parties’ briefs, and after
    having the benefit of oral argument, we grant S&W’s petition for review and
    remand this case to the ARB.
    I.
    A. Facts
    From 1993 until 2004, James Speegle worked as a journeyman painter for
    S&W and other contractors at the Tennessee Valley Authority’s (“TVA”) Browns
    Ferry Nuclear Plant. In 2003 and 2004, Speegle worked for S&W on the Unit 1
    2
    Restart Project inside of the Torus, a large, circular vessel that surrounds the
    plant’s reactor core and flushes water to the core in the event of a nuclear
    meltdown. The project included identifying failed paint coatings in the Torus,
    stripping paint, and repainting. From January 2004 until his termination, Speegle
    served as a foreman of a crew of apprentice painters.
    Until May 2004, S&W used only journeyman painters like Speegle for
    painting the inside of the Torus because the G-55, a TVA manual that set out
    protective painting requirements, specifically called for “journeyman” painters
    who were certified to paint in a “Service Level 1” area. However, in early May
    2004, S&W announced that it would certify “apprentice” painters to work in the
    Torus. Speegle believed that the G-55 only permitted the use of journeyman
    painters and that less experienced painters would jeopardize plant safety. The
    quality of the paint job mattered, as chipped paint or other debris could potentially
    clog pump motors and hinder the cooling process in the event of a meltdown.
    Speegle voiced his safety concerns to his supervisor, S&W’s Super General
    Foreman, Sebourn Childers (“Childers”), who informed Speegle that the TVA
    regulations were being formally modified to call for “coating applicators” rather
    than journeyman painters. S&W’s Lead Civil Superintendent, Rick Gero
    (“Gero”), consulted with site engineers, learned that it was acceptable to designate
    3
    his painters as coating applicators rather than journeyman painters, pursued proper
    procedures to revise the G-55’s language, and began certifying experienced
    apprentice painters who could pass requisite TVA tests. Several times, Speegle
    and other journeyman painters voiced their concerns about allowing apprentices to
    do their work. While some journeyman painters felt that their jobs were being
    threatened by apprentice painters, Speegle objected because of nuclear safety. In
    spite of S&W’s successful effort to legitimately revise the G-55 and the finality of
    the company’s decision, Speegle and other journeyman painters refused to accept
    S&W’s decision, and continued to complain to Childers and Gero. Speegle raised
    the issue to Childers at daily safety meetings. Each time, Childers indicated that
    the matter had been decided and would not be discussed.
    During the safety meeting on Saturday, May 22, 2004, at which time
    Childers presented the official revision of the G-55 that accommodated apprentice
    painters, Speegle told Childers, in a loud voice and in front of several other
    subordinate employees, “You and management can take that G-55 and you can
    shove it up your ass.” [R. 88 at 606.] Childers then stopped the meeting to defuse
    the situation. Another supervisor who heard the comment, Joe Albarado
    (“Albarado”), agreed with Childers that the disrespectful comment warranted
    disciplinary action. The same day, Childers and Albarado discussed the incident
    4
    with Gero by phone. Gero recommended suspension until further investigation.
    Two days later, after taking and comparing Childers’ and Albarado’s written
    statements, Gero decided to terminate Speegle for insubordination.
    While two other S&W employees, James Jones and Santo Chiodo, were also
    fired for insubordination after making similar, disrespectful remarks to
    supervisors, each first received a warning before his termination. Jones, an
    engineer, called a plant official a moron; he also wrote several baseless letters
    criticizing S&W managers and co-workers, calling them names. S&W warned
    him to stop or action would be taken. After Jones screamed profanities at his
    supervisor in front of three or four other employees, S&W terminated him for
    insubordination. Chiodo lashed out at his foreman in front of co-workers and used
    vulgar language. He was warned that his conduct would not be tolerated. After
    another outburst, S&W likewise terminated Chiodo for insubordination.
    B. Procedural History
    Pursuant to the ERA’s provisions, see 42 U.S.C. § 5851, Speegle filed a
    whistleblower complaint with the Secretary of Labor’s Occupational Safety and
    Health Administration (“OSHA”), alleging that S&W violated the ERA by firing
    him for making nuclear safety complaints. S&W formally responded that it
    terminated Speegle for his insubordinate attitude and foul language exhibited
    5
    toward Childers at the May 22, 2004, meeting. OSHA investigated and dismissed
    the complaint. Speegle then appealed and sought a hearing. After receiving
    testimony and evidence, ALJ Richard D. Mills issued a thorough recommended
    decision and order (“the RDO”), recommending that Speegle’s complaint be
    dismissed because the record lacked evidence suggesting that his termination was
    related to his statutorily protected activity. The ALJ found that Speegle engaged
    in protected activity when he complained about apprentice painters working in the
    Torus because he reasonably believed that S&W was violating the G-55 and that
    the apprentice painters were unqualified for the work. The ALJ further found that
    S&W knew about the protected activity and took adverse action against Speegle
    by terminating him. However, the ALJ determined that Speegle did not prove by a
    preponderance of the evidence that his suspension and later termination were
    related to his protected activity.
    The ARB reversed the ALJ’s RDO in its final decision and order (“the
    FDO”), concluding that Speegle’s safety complaints contributed to S&W’s
    decision to fire him. Specifically, the ARB found that substantial evidence in the
    record supported Speegle’s argument that S&W’s reasons for terminating him
    were pretextual and that Speegle was treated more harshly than similarly situated,
    insubordinate employees, namely Jones and Chiodo. Consequently, the ARB
    6
    remanded the matter to the ALJ for findings on Speegle’s damages.1 A different
    ALJ, Patrick M. Rosenow, entered an amended decision and order on stipulated
    damages awarding Speegle back pay, two years front pay in lieu of reinstatement,
    a purged employment file without reference to Speegle’s protected activity and
    discharge, compensatory damages, and damages for future psychiatric counseling.
    S&W appealed to the ARB, objecting to the ARB’s liability determination on the
    grounds that the ARB had exceeded the scope of substantial evidence review and
    that substantial evidence did not support the ARB’s conclusion that Speegle’s
    protected activity caused S&W to suspend and terminate Speegle. The ARB
    summarily affirmed the ALJ’s order on damages as well as the ARB’s earlier FDO
    on liability. Pursuant to 42 U.S.C. § 5851(c), S&W timely filed this petition for
    review with our court, seeking review of the ARB’s decision on liability only.
    Speegle filed a motion to intervene, which we granted.
    II.
    We must review the ARB’s decision pursuant to the standard of review
    outlined in the Administrative Procedure Act. Fields v. U.S. Dep’t of Labor
    Admin. Review Bd., 
    173 F.3d 811
    , 813 (11th Cir. 1999) (per curiam). We will

    S&W could not appeal the 2009 FDO to this court as we would have dismissed for lack
    of jurisdiction. See Fluor Constructors, Inc. v. Reich, 
    111 F.3d 94
    , 95 (11th Cir. 1997).
    7
    overturn the ARB’s findings if they are “arbitrary, capricious, an abuse of
    discretion, or otherwise not in accordance with law” or if the findings were made
    “without observance of procedure required by law.” 5 U.S.C. § 706(2)(A), (D).
    We conduct de novo review of the Secretary of Labor’s legal conclusions, but we
    test the Secretary’s factual findings for substantial evidence. Stone & Webster
    Eng’g Corp. v. Herman, 
    115 F.3d 1568
    , 1571 (11th Cir. 1997).
    III.
    A. The scope of substantial evidence review
    The ERA prohibits employers from taking adverse action against employees
    who report nuclear safety concerns. See 42 U.S.C. § 5851(a). An ERA
    whistleblower complainant must prove, inter alia, that his ERA-protected activity
    was a factor in his employer’s decision to take the adverse action against him.
    Bechtel Constr. Co. v. Sec’y of Labor, 
    50 F.3d 926
    , 933–34 (11th Cir. 1995). The
    complainant’s burden of proof is a preponderance of the evidence. See Dysert v.
    U.S. Sec’y of Labor, 
    105 F.3d 607
    , 610 (11th Cir. 1997). The Secretary’s ARB
    found, in contradiction to the ALJ’s findings, that Speegle proved an inference of
    causation between his protected activity and S&W’s adverse action against him.
    We have previously held that where the Secretary disagrees with the ALJ,
    we review the Secretary’s decision “more critically,” but ultimately, “the decision
    8
    is the Secretary’s[,]” so long as the Secretary supports her decision with
    “articulate, cogent, and reliable analysis.” 
    Herman, 115 F.3d at 1572
    (internal
    quotation marks omitted). In other words, we look for substantial evidence
    supporting the agency’s final decision. See 5 U.S.C. § 706(2)(E). However, in
    2007, the Secretary of Labor revised the ARB’s standard of review of an ALJ’s
    factual findings in an ERA case from de novo review to substantial evidence
    review. See 29 C.F.R. § 24.110(b). As a result, we now show less deference to an
    ARB that disturbs the factual findings of an ALJ. In order to ensure that the ARB
    observed the Secretary’s regulation by reviewing the ALJ’s RDO for substantial
    evidence, we must review the ALJ’s RDO to see if it, rather than the ARB’s FDO,
    was in fact based on substantial evidence.
    Pursuant to the Secretary of Labor’s regulation, the ARB should have
    reviewed the ALJ’s factual findings for substantial evidence. 29 C.F.R. §
    24.110(b). Substantial evidence is “more than a mere scintilla. It means such
    relevant evidence as a reasonable mind might accept as adequate to support a
    conclusion.” Richardson v. Perales, 
    402 U.S. 389
    , 401, 
    91 S. Ct. 1420
    , 1427
    (1971) (internal quotation marks omitted). Thus, substantial evidence exists even
    when two inconsistent conclusions can be drawn from the same evidence. Zahnd
    v. Sec’y of Dep’t of Agric., 
    479 F.3d 767
    , 771 (11th Cir. 2007). The substantial
    9
    evidence standard limits the reviewing court from “deciding the facts anew,
    making credibility determinations, or re-weighing the evidence.” Moore v.
    Barnhart, 
    405 F.3d 1208
    , 1211 (11th Cir. 2005) (per curiam). Although the ARB
    acknowledged that it was bound by the substantial evidence standard, the ARB
    showed little deference to the ALJ’s findings with which it disagreed, and it
    disregarded the ALJ’s conclusions supported by substantial evidence in the record.
    1. Evidence of shifting explanations
    The ARB disagreed with the ALJ’s findings on whether S&W provided
    shifting explanations for terminating Speegle’s employment. S&W documented
    its reason for Speegle’s termination as “insubordination.” [R. 94, Complainant’s
    Ex. 25.] In July 2004, S&W responded to OSHA that Speegle was fired for his
    “insubordinate attitude and foul language” exhibited toward Childers at the May
    22, 2004, meeting. [R. 88 at 833.] The ARB contrasted these explanations with
    Childers’ and Gero’s later testimony that Speegle was fired for his intent to
    disobey procedures, particularly the G-55, and that his use of profanity was not the
    cause of his termination. Furthermore, the ARB was unsatisfied that the ALJ did
    not support its findings with evidence in the record explaining what Speegle’s
    “shove it” comment meant, or what procedures Speegle was unwilling to follow.
    Considering the record anew, the ARB found that there was substantial evidence
    10
    demonstrating that S&W offered different reasons for its action, which in turn
    substantiated the inference of pretext for terminating Speegle’s employment. The
    question for the ARB, however, was not whether the ARB could support
    alternative factual findings with substantial evidence, but whether the ALJ could
    support its original findings with substantial evidence. See 29 C.F.R. § 24.110(b);
    see also Adefemi v. Ashcroft, 
    386 F.3d 1022
    , 1029 (11th Cir. 2004) (explaining
    that a review of factual findings under the substantial evidence standard does not
    consider “whether there is substantial evidence for some other finding that could
    have been, but was not, made” (internal quotation marks omitted)).
    In the RDO, the ALJ explained that it did not find it inconsistent that S&W
    reported “insubordination and foul language” to OSHA, but later said that foul
    language had nothing to do with Speegle’s termination because profanity was
    simply part of Speegle’s insubordinate comment. Next, while it is true the ALJ’s
    RDO does not specifically address what Speegle’s comment meant or how it
    proved his contempt for company procedures, the ALJ most likely saw no need to
    explain how Speegle’s comment (“You and management can take that G-55 and
    you can shove it up your ass”) demonstrated insubordination and contempt for the
    revised procedures. Further, there is very little difference between S&W’s initial
    description of Speegle’s comment as “insubordination” and later description as
    11
    manifesting an intent to disobey or disregard procedures.2 Finally, as the initial
    factfinder, the ALJ was entitled to give weight to Gero’s testimony, which it found
    to be consistent and credible. Gero testified as to his belief that Speegle’s conduct
    warranted termination and to his interpretation of the comment as an indication
    that Speegle would not submit to the G-55. Therefore, the ALJ’s finding that
    S&W did not offer shifting explanations was supported by substantial evidence.
    The ARB did not observe “procedure required by law,” 5 U.S.C. § 706(2)(D), and
    therefore, its decision was “not in accordance with law,” 
    Id. at § 706(2)(A),
    because it failed to review the RDO for substantial evidence.
    2. Evidence of disparate treatment
    The ARB also challenged the ALJ’s conclusions on disparate treatment,
    finding that Jones and Chiodo were comparators because they also lashed out at
    superiors. The ARB gave no weight to the fact that Jones and Chiodo had
    different supervisors. It further rejected the ALJ’s conclusion that Speegle’s
    conduct was distinguishable from Jones’ and Chiodo’s conduct in that Speegle’s
    comment showed his intent to disobey procedures. Lastly, the ARB criticized the
    ALJ’s finding that Speegle’s insubordination was more serious because he made
    2
    “Insubordination” is “the quality or state of being insubordinate: defiance of authority.”
    WEBSTER’S THIRD NEW INTERNATIONAL DICTIONARY 1172 (1986). To be “insubordinate” is to
    be “unwilling to submit to authority: disobedient.” 
    Id. (emphasis added). 12
    his remark in front of subordinate employees. The ARB noted that S&W’s Human
    Resources representative, Fran Trest, conceded that Jones, an engineer, would
    have been expected to conduct himself with the same dignity as Speegle, a
    foreman.
    Again, the ARB did not show deference to the ALJ’s findings that neither
    Jones nor Chiodo were adequate comparators. Testimony and evidence showed
    that Speegle differed from Jones and Chiodo in several ways. First, Speegle
    manifested a different level of insubordination insofar as he not only disrespected
    authority, but also showed contempt for company procedures. Moreover, Speegle
    possessed a different level of influence on co-workers who witnessed the
    insubordinate conduct. Speegle was insubordinate in front of a crew of
    subordinate co-workers who were also expected to submit to S&W’s revised
    procedures. Finally, neither Jones nor Chiodo answered to Childers or Gero as a
    supervisor. Thus, the ALJ substantiated its conclusion with testimony and
    evidence from the record. Therefore, we conclude that the ARB erred, see 5
    U.S.C. § 706(2)(A), (D), by refusing to accept the ALJ’s findings which were
    based on substantial evidence.
    B. Application of Eleventh Circuit Title VII law
    Even if the ARB correctly found that the ALJ’s findings were not supported
    13
    by substantial evidence, we must nevertheless grant S&W’s petition for review
    because the ARB failed to correctly identify and follow our circuit’s Title VII
    precedent in its FDO. See 5 U.S.C § 706(2)(A).
    1. The “nearly identical” standard for comparator misconduct
    The ARB looked to Eleventh Circuit case law to support the proposition
    that Speegle could prove pretext by showing that comparator employees “who
    engaged in similar conduct, but who did not engage in protected activity, were not
    similarly treated.” [R. 119 at 13 (citing Sparks v. Pilot Freight Carriers, Inc., 
    830 F.2d 1554
    , 1563 (11th Cir. 1987)).] The ARB held that to identify a comparator
    employee, “[t]he plaintiff need not prove that the [comparator’s] conduct was the
    same or nearly identical, but only that it was similar.” [R. 119 at 13 (citing
    Anderson v. WBMG-42, 
    253 F.3d 561
    , 565 (11th Cir. 2001)).] The ARB
    acknowledged that Anderson, however, contradicts Silvera v. Orange Cnty. Sch.
    Bd., 
    244 F.3d 1253
    , 1259 (11th Cir. 2001) (holding that a “comparator’s
    misconduct must be nearly identical to the plaintiff’s” (emphasis added)). We
    resolved this conflict in favor of the “nearly identical” standard. Burke-Fowler v.
    Orange Cnty., Fla., 
    447 F.3d 1319
    , 1323 n.2 (11th Cir. 2006) (per curiam)
    (reasoning that we are bound to follow the earliest panel decision on the issue,
    Maniccia v. Brown, 
    171 F.3d 1364
    , 1368 (11th Cir. 1999)). Thus, the ARB relied
    14
    upon a case that we have expressly set aside.
    On appeal, the Secretary and Speegle both argue that this court’s Title VII
    case law is only persuasive authority for the Department of Labor, and therefore, it
    does not matter that the ARB cited Anderson. However, the Secretary’s ARB has
    said that in “inferential cases” like Speegle’s where the parties contest the issue of
    causation (i.e., whether the employee’s protected activity contributed to the
    adverse action), “[the ARB] and reviewing courts routinely apply the framework
    of burdens developed for pretext analysis under Title VII of the Civil Rights Act
    of 1964 and other employment discrimination laws.” Overall v. TVA, ARB Case
    Nos. 98-111 and 98-128, ALJ No. 97-ERA-53, slip op. at *10 (Dep’t of Labor
    Admin. Rev. Bd. Apr. 30, 2001) (emphasis added) (internal quotation marks
    omitted). Our Title VII case law may not be binding, but the Secretary does not
    deny that her agency “routinely” follows it. Furthermore, the Secretary and
    Speegle do not explain what agency law we ought to apply instead of our own.
    Neither do they explain how the ARB intended to depart from our precedent while
    expressly citing our precedent. The Secretary only responds that we should afford
    deference to the ARB’s FDO because Congress has given the Secretary the
    authority to enforce the ERA by formal adjudication. See 42 U.S.C. § 5851(b).
    However, the ARB decision did not construe the ERA, but rather, this court’s Title
    15
    VII case law. If the Secretary cites our precedent, we are obligated to review, and
    if necessary, correct, her application of our precedent. See 5 U.S.C § 706(2)(A)
    (“[T]he reviewing court shall . . . set aside agency action, findings, and
    conclusions found to be . . . not in accordance with law.”); 
    Herman, 115 F.3d at 1571
    (stating that we review the Secretary’s legal conclusions de novo).
    When evaluating an allegation of disparate treatment, we require that a
    comparator be “similarly situated to the plaintiff in all relevant respects.” Rioux v.
    City of Atlanta, Ga., 
    520 F.3d 1269
    , 1280 (11th Cir. 2008) (internal quotation
    marks and alterations omitted). The “quantity and quality of the comparator’s
    misconduct must be nearly identical.” 
    Burke-Fowler, 447 F.3d at 1323
    . “The
    most important factors in the disciplinary context are the nature of the offenses
    committed and the nature of the punishments imposed.” 
    Maniccia, 171 F.3d at 1368
    (internal quotation marks omitted). We ask whether the comparator is
    involved in the same or similar conduct as the plaintiff yet disciplined in a
    different way. 
    Burke-Fowler, 447 F.3d at 1323
    .
    Although the ARB described Speegle’s, Jones’, and Chiodo’s insubordinate
    misconduct as “identical,” [R. 119 at 14], the ARB settled for merely similar
    conduct under Anderson. The record distinguished Speegle’s offense from Jones’s
    and Choido’s offenses. Speegle was himself a leader (foreman) who disrespected
    16
    his supervisor and the company’s procedures in front of his own subordinate
    employees. Thus, the quality of Speegle’s misconduct was distinguishable from
    and not nearly identical to his comparators’ misconduct. See 
    Burke-Fowler, 447 F.3d at 1323
    . Furthermore, the ALJ noted that unlike Speegle, neither Jones nor
    Chiodo had Childers or Gero as his supervisor. While this fact is not dispositive
    alone, it is useful to further distinguish employees’ situations. Thus, we conclude
    that the ARB erred in concluding that Jones and Chiodo were comparators and
    that Speegle was treated differently from similarly situated S&W employees.
    2. The import of an employer’s honestly held belief about an employee’s
    misconduct
    In deciding that S&W provided shifting explanations for Speegle’s
    termination, the ARB discredited Gero’s testimony that he interpreted Speegle’s
    comment to mean that Speegle would not follow the G-55. S&W argues that the
    ARB erred in failing to consider what Gero and other supervisors honestly
    believed that Speegle’s comment meant. Where an employee argues that he did
    not actually engage in misconduct, we have held that an employer may rebut this
    allegation by showing its good faith, honest belief that the employee violated a
    rule. Elrod v. Sears, Roebuck & Co., 
    939 F.2d 1466
    , 1470 (11th Cir. 1991)
    (reasoning that courts do not reexamine business decisions, and that “our inquiry
    17
    is limited to whether the employer gave an honest explanation” of the adverse
    action (citation omitted)); Jones v. Gerwens, 
    874 F.2d 1534
    , 1540 (11th Cir.
    1989).3 Thus, even if Speegle’s comment meant something else, or nothing at all,
    and even if Speegle never actually intended to disobey orders or procedures, Gero
    testified, and the ALJ found it credible, that he understood Speegle’s
    insubordinate comment to mean that Speegle would not comply with the new
    policy and procedures. We conclude from the record that the ARB erred in
    discrediting Gero’s consistent testimony about his interpretation of Speegle’s
    comment.
    C. The propriety of remand to the agency
    As a final matter, S&W asks this court to reinstate the ALJ’s RDO rather
    than remanding this case to the ARB for further proceedings. S&W contends that
    remand would be futile and nothing more than a formality. The Secretary and
    Speegle ask that we remand the case to the ARB for two reasons: first, to afford it
    the opportunity to review the RDO in light of our decision; and second, to allow
    the ARB to consider Speegle’s additional arguments that the ARB did not
    3
    The ARB did not discuss Elrod, Jones, or any other Eleventh Circuit law concerning an
    employer’s honestly held belief about the employee’s misconduct. In her brief, the Secretary
    does not dispute our case law on this point. She simply defends the merit of the ARB’s finding
    that shifting explanations negate the credibility of Gero’s testimony concerning his honestly held
    belief. Thus, the Secretary’s arguments depend upon our agreeing with her position that the
    ALJ’s RDO was not supported by substantial evidence. As 
    discussed supra
    , we do not agree.

    consider when it first reviewed the RDO. In addition to challenging the ALJ’s
    findings concerning shifting explanations and disparate treatment, Speegle also
    argued that the ALJ ignored other circumstantial evidence showing pretext:
    particularly, that Childers essentially admitted that Speegle’s history of safety
    complaints influenced his recommendation to terminate Speegle’s employment;
    that Childers attempted to intimidate other painters supporting Speegle after
    Speegle filed his complaint; and finally, that the Nuclear Regulatory Commission
    and TVA eventually validated Speegle’s safety concerns.4 The ARB never
    considered these arguments after it agreed with Speegle that the record
    substantiated Speegle’s arguments on shifting explanations and disparate
    treatment.
    It is an established principle of administrative law that an appellate court
    should not “intrude upon the domain which Congress has exclusively entrusted to
    an administrative agency.” INS v. Ventura, 
    537 U.S. 12
    , 16, 
    123 S. Ct. 353
    , 355
    (2002) (per curiam) (quoting SEC v. Chenery Corp., 
    318 U.S. 80
    , 88, 
    63 S. Ct. 454
    , 459 (1943)). Thus, “the proper course, except in rare circumstances, is to
    remand [a matter] to [an] agency for additional investigation or explanation.”
    4
    The ARB specifically noted in the FDO that it was not reaching these additional
    arguments. [See R. 119 at 10 n.63.]

    Gonzales v. Thomas, 
    547 U.S. 183
    , 186, 
    126 S. Ct. 1613
    , 1615 (2006) (per curiam)
    (quoting 
    Ventura, 537 U.S. at 16
    , 123 S. Ct. at 355). In both Gonzalez and
    Ventura, the Supreme Court reversed the Ninth Circuit for failing to remand each
    case to the Board of Immigration Appeals where that agency had yet to consider
    issues in the first instance. 
    Gonzalez, 547 U.S. at 186–87
    , 126 S. Ct. at 1615;
    
    Ventura, 537 U.S. at 17
    ; 123 S. Ct. at 356. We have found the existence of rare
    circumstances and decided an issue in the first instance only when “the undecided
    issue [was] legal, not factual.” Calle v. U.S. Att’y Gen., 
    504 F.3d 1324
    , 1330 (11th
    Cir. 2007). The unresolved issues in the instant case are based on factual findings
    and will require the ARB to consider whether the ALJ’s RDO was based upon
    substantial evidence. See 29 C.F.R. § 24.110(b). For these reasons, we must
    remand this case for further review of Speegle’s additional arguments which the
    ARB did not consider in its FDO.
    IV.
    In summary, we conclude that the ARB erred by reviewing the ALJ’s
    decision de novo rather than observing the Secretary’s regulation requiring
    substantial evidence review. We also conclude that the ARB failed to follow
    Eleventh Circuit precedent when analyzing its contrary factual findings.
    Therefore, we grant the petition for review, and remand the case to the Secretary
    20
    for further proceedings consistent with this opinion.
    PETITION GRANTED AND REMANDED.
